Habitat.

Forest species noted on tree trunks and leaves.

Remarks.

When disturbing, actively fast flying among trees; during flight shows bright orange abdomen coloration. Taxonomical status of both subspecies of Therates coracinus noted in Mindanao (spp. Therates coracinus and Therates coracinus ssp. fulvescens Wiesner, 1988) should be revised including molecular data as they probably represent separate species or synonyms.
